ANTISEPTIC TELEPHONE-MOUTHPIECE.

To all whom 'it may concern.'

Be it known that I, IRVING S. RosENBLA'r'r, citizen of the United States, residing in the city and county of San Franeiscoand State of California, have invented new and useful Improvements in. Antiseptic Telephone Mouthpieces, of which the following is a specification.

My invention relates to a telephone antisept-ic mouth-piece, and is especially de signed to provide an efficient, antiseptic attachment byl which the disagreeable and dangerous effect arising from the passage of the breath of the user through the telephone may -be avoided by other users of the instrument. The device also serves to prevent the user from placing the mouth so near to the mouth-piece as to render the conversation indistinet.

The invention consists of t-he parts and the combination and construction of parts 'hereinafter more fully described and claimed,

having reference to the accompanying drawings, in which--V Figure l is an elevation ofmy invent-ion.

Fig. 2 is an endview illustrating my invention. Fig. 3 is a section of my invention.

Various devices have been heretofore employed to purify, disinfect, and prevent dis-v agreeable or dangerous results from the general use of telephones by a great variety of people, suchl devices consisting usually of disks of absorbent material located within the mouth-piece or of annular casings of such material surrounding the interior of themouth-piece. These devices do not present a sufficient surface for the proper purilication of the apparatus.

In my invention, if. form the mouthpiece A, preferably of glass of' the usual form, and to the inner and smaller end of the glass is secured a rim of metal which may be secured by expanding it within the glass, or any other suitable manner. The end of this rim 2 extends outwardly and is screwthreaded as shown, so that the nuuith-piece may be readily attached to or disconnected from the instrument. The outer end of this mouth-piece is formed with lugs 3, which are preferably spaced equidistant around tho edge of the flaring outer end, and slightly 'raised above 1t.

4 is a disk perforated with small holes suiiiciently numerous to allow the air vibrations to pass freely therethrough.

' The rim or ring 2 h as its inner end closed Specification of Letters Patent.

Application led February 28, 1911. Serial No. 611,363.

or provided with an arched perforated disk 5 and between the two disks I place a mass of cot-ton or equivalent loose porous and absorbent material Which fills the entire space between the perforated disks 4; and 5, thus providing a body of considerable depth. This absorbent material may be saturated from time to time with any suitable antiseptic and, being of extremely loose texture it will no't interfere in any way with the vibrations caused by talking into the instrument. At the same time, the distance between the disks and the very considerable mass of sterilizing material, will insure the utmost cleanliness of the interior of the mouth-piece.

The disk 4 is formed with notches 6 cor responding with the position of the lugs 3,

so that the disk may be introduced by bringing the notches to register with the lugs 3,

then pushing the disk downwardly until itpasses the lugs, after which it may be slightly turned in the channel foi-'med between the lugs and the divergent interior of the part A, so that it will be easily held in position and may` be as readily removed by turning the disk, so that the notches will again register with the lugs 3. By reason of these lugs being above the exterior of the periphery of the mouth-piece, the disk itself will be broughtto the extreme outer periphery and the position is such that the operator will be prevented from placing the mouth so near to the instrument as to render the tones of the voice indistinet.

Having thus described my invention, what I claim and desire to secure by Letters Patent isl. A telephone mouth-piece consisting of an exterior shell having a sc reW-threaded extension and perforated disk at the smaller end, a perforated disk at the outer end, and a filling of sterilized absorbentmaterial occupying the entire space between the disks and sides.

2. The combination in a telephone mouthpiece of a bell-shaped glazed shell portion, a metal, exteriorly screw-threaded nipple fixed to the inner end and a perforated disk carried thereon, a second perforated disk and means detachably securing it to the outer end of the shell and a mass of porous absorbent, sterilized material packed into the space between the disks.

3. A telephone mouth-piece consisting of a glazed bell-shaped shell, a metal exteriorly of the shell, a second perforated disk fittedthreaded nippiehaving a perforated disk at its inner end, and secured to the inner end to the outer end of the shell and having peripheral notches, and a mass of porous absorbent, sterilized material packed into the space between said disks, said shell having peripheral lugs with which said notches may engage.

4. A telephone mouth-piece consisting of a glazed bell-shaped shell having lugs extending inwardly from the outer' periphery, a perforated correspondinalv notched disk engageable with said lugs, an exteriorl'y screw-threaded nipple having a perforated 15 transverse disk x'ed to the inner end of the shell and a filling of porous absorbent, sterilized material occupying the space within the shell and between the disks.
